AMPLIFICATION-TYPE SOLID-STATE IMAGE PICKUP DEVICE
Document Type and Number:
Japanese Patent JP2006135089
Kind Code:
A
Abstract:

To provide an amplification-type solid-state image pickup device capable of reducing image quality deterioration.

The amplification-type solid state image pickup-device comprises at least a photoreceiver unit 10 which is formed by one-dimensionally or two-dimensionally disposing on a semiconductor substrate 7 a plurality of pixels that convert incident light into a signal charge, and output an electrical signal according to the amount of signal charge; reading means for sequentially reading electrical signals from each of the plurality of pixels; a noise removing circuit 11 for reducing aliases of the electrical signals read by the reading means; and a first shield layer 1 disposed on the upper part of the photoreceiver unit 10 for restricting the entrance of light into parts other than a photoelectric conversion unit 10a of the pixel. A second light shield layer 2 for restricting the light entering the noise removing circuit 11 is further provided on the upper part of the noise removing circuit 11.
